Title: Motor
Inventor: NIIKURA ISAMU
IPC: H02K16/00
Filed: 1983-05-09
Abstract: PURPOSE:To enable to control in two-dimensions with one motor by forming an inner rotor and an outer rotor which differentially operate by repelling or attracting magnetic field, and producing output shafts from the both rotors. CONSTITUTION:An output shaft 2 is rotatably supported to a base 1, and an inner rotor 4 made of a magnetic unit 3 is secured to the shaft 2. An outer rotor 6 having an output shaft 5 is rotatably provided around the rotor 4. An AC power source is applied to an input terminal 13. Thus, a coil 8 is energized through a slip ring 10 from a brush 11. As a result, a repelling or attracting magnetic field is generated between the unit 3 of the rotor 4 and the field core 7 of the rotor 6, and the rotors 4 and 6 and hence the output shafts 2, 5 start rotating in opposite direction to each other.

Title: Polarity detecting method for polar capacitor
Inventor: SUZUKI TOSHIKATSU
IPC: H01G13/00
Filed: 1991-03-20
Abstract: PURPOSE:To surely detect polarity of a polar capacitor. CONSTITUTION:In this polarity detecting method for a polar capacitor, polarity is detected by measuring at least one bias characteristic of capacity change rate, tan delta or equivalent series resistance. As the bias characteristics of capacity change rate, tan delta and ESR are greatly different whether it is in the forward direction or reverse direction, polarity of the polar capacitor can be surely detected by measuring these bias characteristics.

Title: Am stereophonic receiver
Inventor: WATANABE KAZUO
IPC: H04H1/00
Filed: 1982-05-17
Abstract: PURPOSE:To vary a threshold value for detecting a break of a carrier in response to variation in the level of an input signal, by providing a muting detecting circuit which varies a threshold value for the transmission and inhibition of the signal of a gate circuit. CONSTITUTION:A gate circuit 16 is provided on the input side of a peak detector 11 to inhibit the transmission of such a carrier that the AM modulation rate of an intermediate-frequency amplified 1F2 exceeds about 80%. Consequently, a detection signal regarding a carrier having a > about 85% AM modulation rate as a break of the carrier appears at the output of the peak detector 11. Further, a burst noise is integrated by a low-pass filter 9, so recovery time is extended. Therefore, a carrier break detection signal generated by the peak detector 11 is passed through a delay circuit 12 which extends only the recovery time to put a muting circuit 13 in operation and only an OR signal is outputted temporarily from a matrix circuit 15 to perform automatic switching to monaural reproduction, eliminating the burst noise.

Title: Preparation of rodlike fiber-reinforced plastics
Inventor: HIROI TSUTOMU
IPC: B29C57/00
Filed: 1981-05-28
Abstract: PURPOSE: To obtain the title plastics with a good defoaming effect, while inhibiting the generation of voids, by forming a reinforcing fibrous material impregnated with thermosetting resin under a B-stage condition into a rodlike body, precuring said body with heat, winding a heat-contractible porous sheet around the precured rodlike body, and further heating said body to a C-stage.  
     CONSTITUTION: A reinforcing fibrous material (e.g. carbon fiber) impregnated with thermosetting resin (e.g. epoxy resin) under a B-stage condition (a state at which the resin softens and fluidizes but not melts on heating) is formed into a rodlike body by rolling or the like. Said body is then heated (preferably at a temperature lower by 30W50°C than the curing point of the resin used), to precure the resin. Thereafter, a heat-contractible porous sheet material (such as a textile of synthetic fiber having a contraction ratio of 10% or more at a resin- curing temperature) is wound around the rodlike body, while proper tension is being applied thereto. The resin is heted and fluidized into a C-stage under the condition where pressure is applied to the rodlike body by squeezing it with the thermal contraction of the sheet material. In this way, a rodlike fiber-reinforced plastics is obtained.

Filed: 1988-03-31
Abstract: PURPOSE:To perfectly prevent irregular hulling and polishing by imparting sufficient pulsating and stirring actions to grain, by forming both of a porous wall polishing cylinder and a grain polishing rotary element in a multistage fashion different in diameter. CONSTITUTION:The grain supplied to the spiral rotary element from the grain supply part of a vertical shaft and frictional cutting type grain polishing machine is sent by the spiral rotary element and hulled in the lower and upper grain polishing chambers 6A, 6B formed by a perforated wall bran removing polishing cylinder 2 and lower and upper friction grain polishing rotary elements 5A, 5B to be discharged to a grain discharge part. At this time, the pressure of grain is varied at the different diameter parts of both of the polishing cylinder 2 and the polishing rotary elements 5A, 5B and grain receives large pulsating and stirring actions to revolve. As a result, the grain receives sufficient hulling/polishing action as a whole in a grain polishing chamber 6C. When the cross-sectional areas are controlled at the different diameter parts by a resistance apparatus 37, hulling and polishing can be performed by desired hulling/polishing pressure.

IPC: H01Q1/48
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a microstrip antenna with simple structure which is able to inhibit diffraction waves from the end part of a ground conductor. SOLUTION: In a microstrip antenna, a radiation element 105 is installed on the surface of an antenna substrate 102, and a ground conductor 103 is installed at the rear face. The ground conductor 103 is sandwiched by the antenna substrate 102 and a high frequency amplification circuit 104. Non-feeding elements 107-2 and 107-1 are installed at the end parts of the antenna substrate 102. A width 108 of the non-feeding element 107-1 is set electrically to half the wavelength of an electromagnetic wave to transmitted/received. Consequently, the phase of a diffraction wave generated from the radiation element 105-side of the non-feeding element 107-1 and the diffraction wave discharged from a part along the end part of the antenna substrate 102 are in a relation such that they mutually cancel.  Thus, the diffraction waves are mutually cancelled, and the diffraction waves as the microstrip antenna as a whole is suppressed.
